Jose Mourinho's Manchester United slumped to an embarrassing defeat in the opening game of their pre-season tour of China.

Not even a shock appearance by England sensation Marcus Rashford, who Mourinho had claimed would not feature on the tour, could save United from such a heavy loss.

Borussia Dortmund may be two weeks ahead of United in terms of their pre-season preparation, but that alone could not explain the result, which has left Mourinho with much to ponder ahead of the new campaign.

The debilitating 102°F temperature and bone dry pitch in the Shanghai Stadium did little to help United's cause, but they were slow in body and mind, deservedly losing by the margin they did.
